In Mario & Luigi: Paper Jam, Mario & Luigi: Superstar Saga + Bowser's Minions and Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey, most of the bosses, along with Birdo in Mario & Luigi: Superstar Saga (once Popple is defeated before her) and Princess Shroob in Mario & Luigi: Partners in Time, automatically get this status whenever their health is low enough. For the rest of the battle, they have more attacks, their POW and SPEED increase (alongside DEF in Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey), and some bosses will perform multiple attacks in a single turn. Regular enemies, such as Choombas, go through a similar phase when fired up by Coalbits, making them deal more damage, move faster, and glow red.
